Seminar’s Target

Europe wants to become climate-neutral by 2050 and already save 55% of greenhouse gases by 2030 compared to 1990. The EU Climate Act sets these targets in law for the first time. For large parts of the European steel industry, these targets mean a far-reaching technological change. The technical solution has been found and is: Replace coal with hydrogen! But how does the new process route work in detail? What are the challenges? In three days, the seminar will provide a technical overview of the biggest technology change in the steel industry for decades.

Target Group

Two thirds of the world's crude steel production runs through the converter. The converter will also take its place in future CO₂-neutral steel production in combination with direct reduction and the OBF. In addition to this new future role, the current challenges and trends of the converter will of course also be content of this seminar: scrap qualities, tramp elements, modelling and CFD as well as refractory technology. The programme will be rounded off with the most important fundamentals such as thermodynamics, reaction kinetics and heat and mass balance.

Our target groups are:

• Steel shop operating staff
• Employees in R&D and transformation

Aim

The aim of this the­or­et­ical and prac­tical seminar is to provide par­ti­cipants with an in-depth under­standing of the pro­cesses involved in sec­ondary metal­lurgy. Based on special fun­da­mentals, the indi­vidual reactors for sec­ondary metal­lur­gical treat­ment and their tasks will be explained in detail. There will also be an outlook on hydrogen-based green steel pro­duc­tion. Dis­cus­sions and teamwork exer­cises will round off the range of lectures.

Content

• Overview: Tasks of modern secondary metallurgy
• Materials technology’s impact on process metallurgy
• Chemistry crash course: How to read phase diagrams
• Thermodynamic and kinetics for secondary metallurgy
• Fluid dynamics in the ladle
• Kinetics of special reactions in secondary metallurgy
• Deoxidation

Target Group

The electric arc furnace is taking on a completely new impor-tance in the CO₂ neutral, hydrogen-based process routes of steel production and will play a central role. This role also poses new metallurgical challenges. The aim of the seminar is therefore also to highlight these tasks and possible solutions – such as the OBF. However, the focus will be on the electrotechnical fundamentals of the electric arc furnace and the current state of automation technology. Presentations on the supply network, furnace transformers, energy balances and new energy supply concepts round off the programme.

Target Group

The wear of refractory materials in the secondary metallurgy is particularly high. These high wear mechanisms are complex, but mainly caused by slags. High temperatures, long-terming treatment and turbulences of stirring gas are also important factors for wear and failures.
